Snap switch

Abstract

A snap switch comprises a control button, a control rod slidable with the control button via a spring, two pairs of contacts associated, respectively, with two pairs of terminals, the two contacts of each pair of contacts being connectable by resilient conducting means under the action of a setting spring fixed to the control rod and to these resilient conducting means. The two contacts of one pair of contacts are borne by two pivotable conducting plates, biased by resilient means for connecting the two contacts borne by the conducting plates to their respective terminals. The conducting plates can be pivoted under the action of the control button and against the action of the resilient biasing means for disconnecting the two contacts borne by the conducting plates from their respective terminals.

What I claim is: 
     
       1. A snap, switch, comprising a control button, a spring, a control rod slidable with the control button via said spring, first and second pairs of contacts, first and second pairs of terminals associated with said first and second pairs of contacts, respectively, resilient conducting means, a setting spring fixed to said control rod and to said resilient conducting means, the two contacts of each pair of contacts being connectable by said resilient conducting means under the action of said setting spring, the two contacts of the first pair of contacts being able to be electrically disconnected from their respective terminals by said control button when it is pushed in completely against the action of said spring of said control rod, two conducting plates pivotally mounted in the switch, each of said conducting plates bearing one of the two contacts of the first pair of contacts and resilient means for biasing said conducting plates toward said first pair of terminals and thus connecting electrically said first pair of contacts to first pair of terminals, whereby said conducting plates can be pivoted under the action of said control button and against the action of said resilient biasing means for electrically disconnecting said first pair contacts from their respective terminals. 
     
     
       2. A switch as claimed in claim 1, wherein said two contacts of the first pair of contacts are each disposed on the pivoting axis of said pivotable conducting plates.
